COLUMBUS, Ohio — New state restrictions have barred a Cincinnati hospital from accepting federal money to help sign people up for insurance under President Barack Obama's health care law. Children's Hospital Medical Center had planned to enroll the uninsured through its inner-city location and two satellite offices. But the hospital recently notified the Obama administration that it couldn't take the $124,419 grant to be a so-called navigator because changes in Ohio law made it ineligible, said hospital spokesman Terry Loftus. The hospital is among a few navigator grantees that have notified the U.S. Health and Human Services Department that they wouldn't be taking the money.
